Chapter 6: UEFI BIOS
INT19 (Interrupt 19) Trap Response
Interrupt 19 is the software interrupt that handles the boot disk function. When this item is
set to Immediate, the ROM BIOS of the host adaptors will "capture" Interrupt 19 at bootup
immediately and allow the drives that are attached to these host adaptors to function as
bootable disks. If this item is set to Postponed, the ROM BIOS of the host adaptors will not
capture Interrupt 19 immediately and allow the drives attached to these adaptors to function
as bootable devices at bootup. The options are
Immediate
and Postponed.
